1450018: CVE-2017-7481 ansible: Security issue with lookup return not tainting the jinja2 environment
An input validation flaw was found in Ansible, where it fails to properly mark lookup-plugin results as unsafe. If an attacker could control the results of lookup() calls, they could inject Unicode strings to be parsed by the jinja2 templating system, resulting in code execution. By default, the jinja2 templating language is now marked as 'unsafe' and is not evaluated.
